Non-linear Damper

Most Mass-Spring-Damper system models assume that the stiffness and damping coefficients are constant. In real engineering systems, this would be very rare.

This example shows how you can create a custom component that changes the system equations to allow you to enter stiffness and damping values as a input signal to the block. The example uses an external data file of damping values, varying over displacement, as a lookup table to provide the appropriate damping factor.
